PACKNG SHEET FOR rGLASS JARS ANDERE LIKE. y

application mea February 11, 1922. serial ab` senese i T0 all (whom it may concer/n.'

Be it known that I, HARRY J. THOMPSON, a citizen of the United States', residing at San Francisco, in. the county of San Fran-A This invention relates to packing sheets.

designed primarily for use in holding glass jars while in transit or while being handled inquantities so that they will not be broken through rough handling.

One of the objects of the invention is to provide packing sheets or trays of novel form designed to act as cushions and also as spacing means for holding the jars or the like properly positioned at all times.

A, further object is to provide packing sheets preferably formed of paper pulp molded to proper shape and capable of being assembled readily for the purpose of properly positioning the jars or other articles therebetween.

Another object is to provide packing sheets which'can be disposed in superposed relation so that several layers or groups of jars or similar articles can be packed in one create or container without being injure-d.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de-V scribed and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preerred form of the invention has been shown.

In said drawings- Figure 1 is a plan'view of av portion of one of the packing sheets.

Figure 2 is a. section on line 2 2, Figure 1.

Figure y3 is a section on line 3 3, Figure 1.'

similar to Figure 4 but showing ran inter-- posed. or intermediate packing sheet combined with the top and bottom sheets. 4

Y Figure 6 is a plan view of the interme-i bottoms of jars to be packed. `As-shown in. Figure 2 the bottoms of the seats 2 are preferably rounded to conform with the contour vot the bottomsof the jars to be placed therein. Furthermore the walls between the seats aredepressed. as shown at 3 thus to provide connecting ribs between the seats to reenforce or stillen the sheet between the seats. Ars the entire sheet is molded of paper pulp or a like porous substance the recessed face thereof will present a smooth finished appearance but the opposed face of each sheet is preferably rough and unfinished as clearly indicated in Figures 2 and 3. This unfinished or rough surface provides numerous projections or nodes some of which have been indicated at 4 whereby when two sheets are placed back to back the said nodes act as cushioning means to absorb shocks not otherwise absorbed by the structure of each of the sheets.

All of the sheets can be similarly made, it being designed to arrange them in pairs, the upper sheet of each pair being inverted as shown in Figure 4 so as to receive the top portions of the jars carried by the lower sheet. In Figure 4 one of the jars has been indicated at J. Obviously if articles other than jars are to be used the upper sheet of each pair would have to have seats therein so shaped and proportioned as properly to fit the upper ends of the articles mounted on the lower sheet. Where both ends of the held article are of approximately the same diameters, however, only one style of packing sheet need be used.

After one group of jars or similar articles has been positioned betweentwo sheets as shown in Figure 4, another pair of sheets with jars or the like therebetween can be placed thereabove as will be obvious. It is of course to be understood that all of these packing sheets with the articles therebetween can be placed within a suitable container and that after the articles have thus been located Referring'to the figuresby characters ofY the container can be transported from place o tofplace'fand subjected to rough handling with littleVv danger of injuring" the vcontents of the container.

V,Under some circumstances itis desirable to protect the intermediate portions'of the Vheld articles and for this purposeanintermediate packing sheet such as shownV at 5 in Figures 5, 6 and 7 can be used. ,This sheet is likewise formed of paper pulp or the like and lis made quite thick lso as to span kthe spacebetween the top and bottom packing i sheets engaging the articles. 'Openings are i formed within the intermediate sheet 5 and are proportioned-to receive the intermediate portionsof thev jheld jars or-other Vparticles. With' partsassembled vas shown in Figure 5' the y,danger of breakage is' almost entirely eliminated-x Y Whil paper. .pulp is; p1-efemb1yuedlin the formation of the packing sheets it is to be Y understoodfthat these sheets can be ymolvc'led 30y molded andhaving spaced depressions therein, the vdepressions in oneof'the sheets constituting seats forthe lower endsof articles Y lto be packed'and the depressions in the other sheet constituting seats for the upper ends ofthe said? articles, the said'sheets': being spaced apart, and an interposed protecting sheet ofyibrous cushioning material bridg-k ing fthe 4space betweenithe upper and lower packingsheets andhaving openings therein in which are seatedy the intermediate porations of the packed articles. Y f v rv2. A structure of the class described including oppositelv disposed packing lSheets Y of brouscushioning material molded and-V having opposed recesses therein constituting seats orthe opposed ends of articles therebetween, said sheets `being spaced apart,v and an intermediate sheetfconstituting spacing o means.betweenV the lirst namedjsheets and Y ,vhavingopenings therein through whiclithe ypacked articles extend, said intermediate sheet being toi-ined of ibroiis cushioninginafv terial.

In testimony that I claim the foregoing o as my own, I have hereto aii'iXed my signature in the presence of two witnesses.Y
